CABLE CLAMP.

Application filed March 8, 1928. Serial No. 260,176.

The present invention is directed to i1nprovements in cable clamps.

The primary object of the invention is to provide a device of this character so constructed that the cable will be firmly gripped, the construction being such that the gripping action will be increased as strain is placed upon the cable.

Another object of the invention is to provide a device of this character wherein the clamping jaws are slidably connected in order that they will move longitudinally the same distance, thus assuring that the cable engaged therebetween will be firmly and evenly gripped.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a side view of the device, partly in section.

Figure 2 is a sectional viewon line 2-2 of Figure 1.

Figure 3 is a sectional view on line 3-3 of Figure 1.

Figure 4 is a sectional view on line 4 4 of Figure 3.

Figure 5 is a sectional view on line 5-5 of Figure 3.

Corresponding and like parts are referred to in the following description and designatcd in the several views of the drawing by like reference characters.

Referring to the drawing, 1 designates a body having an eye 2 formed in one end thereof for the attachment of a drag cable, ,or the like.

The body is provided with lateral flanges 3 which terminate in inturned flanges ls-4t which form in conjunction with the flanges 3 grooves 5-5, said grooves having convcrged walls 6-6.

A pair of wedge shaped jaws 7-7 are em ployed and have their outer walls inclined for slidably engaging .the walls 6-6, the inner or confronting faces of said jaws hav ing cable gripping jaws 88 formed longitudinally therein.

These jaws have formed in their outer faces inclined grooves 9-9 in which are slidably engaged the set-screws 10-10 carried by the flanges Obviously those set screws will maintain the jaws in the grooves 55 and will limit the longitudinal sliding movement thereof.

To the major end of one of the jaws 7 is lined a plate 11 having a lateral bar 12 which carries a lug 13 which is adapted to slide in a transverse groove 14 formed in the major end of the companion jaw, thus slidably interlocking said jaws.

By slidably interlocking the aws in this manner they will be compelled to slide simultaneously and the same distance when moved longitudinally of the body, the sliding interlocking connection in no way interfering with the lateral sliding of said jaws.

It will be obvious that when the cable 15 is engaged within the grooves 8-8 of the jaws 77 that strain upon the same will cause the jaws to tightly grip the cable in order that accidental disengagement thereof from between the j awswill be positively prevented.

Since the confronting faces of the flanges 8 are spaced the cable can conveniently be passed therebetwcen for engagement between the jaws, it being of course understood that the jaws will be spread upon moving the same rearwardily.

Having thus described the invention, I claim:

1. A cable clamp, comprising a body having opposed grooves therein, said grooves having convergingly arranged walls, jaws having tapered faces for slidably engaging said walls, a bar carried by one jaw, a lug carried by the bar, the other jaw having a groove therein for slidably receiving said lug, as and for the purpose set forth.

2. A cable clamp, comprising a body including flanges and opposed grooves, a aw slidable in each groove, said jaws having grooves formed therein, and set screws carried by the flanges for slidably engaging the grooves of the jaws.

In testimony whereof I aflix my signa-v ture.
